Misconception: Most people who undergo metabolic and bariatric surgery regain their weight.
Truth:
While up to 50% of patients may regain a small portion of weight (approximately 5%) two or more years after surgery, the majority of patients maintain significant, long-term weight loss. Research defines “successful” weight loss as achieving and maintaining at least 50% of excess body weight loss, although many patients measure success by improved health and quality of life. Longitudinal studies consistently demonstrate that bariatric surgery leads to sustained weight loss, far surpassing non-surgical weight-loss methods.
Misconception: The risk of dying from bariatric surgery is higher than the risk of dying from obesity.
Truth:
Obesity significantly shortens life expectancy due to its association with life-threatening conditions like type 2 diabetes, hypertension, and heart disease. Data from nearly 60,000 bariatric patients shows that the risk of death within 30 days of surgery is only 0.13%—lower than for common procedures like gallbladder removal or hip replacement. Long-term studies reveal that bariatric surgery reduces mortality rates by up to 89%, with dramatic decreases in deaths from diabetes, heart disease, and cancer. For most patients, the benefits of bariatric surgery far outweigh its risks.
Misconception: Bariatric surgery is an “easy way out.” People just need diet and exercise to lose weight.
Truth:
Severe obesity resists long-term weight loss through diet and exercise alone due to biological factors. Research confirms that bariatric surgery is the most effective method for sustained weight loss in individuals with severe obesity. Unlike dieting, which often lowers calorie-burning capacity and increases hunger, bariatric surgery alters gut hormones, enhances feelings of fullness, and helps maintain energy balance. These biological advantages allow patients to achieve and sustain significant weight loss, improving overall health and quality of life.
Misconception: Many bariatric patients develop alcoholism after surgery.
Truth:
Only a small percentage of bariatric patients report alcohol issues after surgery, and most of these individuals had pre-existing alcohol problems. Bariatric surgery can increase alcohol sensitivity, causing quicker intoxication and higher blood alcohol levels. Patients are advised to avoid alcohol during rapid weight-loss phases, drink cautiously, and seek help if alcohol becomes problematic. Comprehensive pre- and post-surgery counseling minimizes the risk of alcohol-related issues.
Misconception: Bariatric surgery increases the risk of suicide.
Truth:
People seeking bariatric surgery often experience depression, anxiety, and low self-esteem due to severe obesity. Surgery typically improves psychological well-being, yet a small number of patients with pre-existing mental health conditions or significant stressors may face heightened suicide risk post-surgery. This is why psychological evaluations and ongoing support are integral parts of bariatric programs to ensure patient safety and well-being.
Misconception: Bariatric surgery leads to severe vitamin and mineral deficiencies.
Truth:
While bariatric surgery can impact nutrient absorption, deficiencies are preventable with proper supplementation and regular follow-ups. Nutritional guidelines tailored to each procedure help patients maintain healthy levels of vitamins, minerals, and proteins. Most bariatric programs require routine monitoring to detect and address any potential deficiencies early, ensuring long-term health and vitality.
Misconception: Obesity is just an addiction to food, like alcoholism or drug dependence.
Truth:
Obesity is a complex, multifactorial disease influenced by genetics, hormones, metabolism, environment, and lifestyle. While food addiction may play a role for some, most cases of obesity involve energy imbalances and metabolic changes that promote fat storage and increase hunger. Obesity is also a progressive condition, with weight gain triggering biological changes that make further weight gain more likely. Treating obesity requires a holistic approach, addressing physical, psychological, and metabolic factors rather than simply viewing it as an addiction.
Key Takeaway:
Bariatric and metabolic surgery is a powerful, evidence-based treatment for severe obesity and its related health conditions. By addressing the biological, hormonal, and metabolic drivers of obesity, surgery offers patients the opportunity to achieve sustainable weight loss, improved health, and a better quality of life.
